I know that
Zelnorm has been prescribed for stomach problems, but I would also
look into a doctor who specializes in type 1 diabetes and gastro problems. In my personal opinion, this is a very underdiagnosed problem. There are new drugs that help with nausea and other problems with the gut.
I would like you to follow LRS's advice for a contact with JDRF's Online Diabetes Support Team. Please mention "gastroparesis".
